Cementum deposition is the desired tissue response at the apical foramen after root canal therapy. Bone resorption, formation of a cyst, and scar tissue formation are all unwanted outcomes. Bone resorption can cause weakening of the tooth structure, formation of a cyst can lead to infection, and scar tissue formation can impede healing and cause discomfort. On the other hand, cementum deposition helps to seal off the apex of the root and promotes healing of the surrounding tissue. It is essential for a successful root canal treatment.
